What is true of this model and changes how you fix it
- What it isA portable controller (model SKF3R0-29) for arming/disarming and sending a Panic signal, assigned to exactly one ADT+ app user during setup.
- RangeADT states range varies with house construction but is generally sufficient within roughly 75 feet of the ADT Base.
- Panic behaviorOn a self-monitored system, ADT documents the Panic alarm as sounding locally only, with no emergency-service dispatch — the Panic feature can also be disabled on the remote entirely.
- PowerOne CR2450 coin-cell battery, included.
- What owners run intoReports include a fob that works only close to the panel, a flat coin cell and a lost fob that still has access.
- How to approach a faultFit a fresh coin cell, enrol it again and delete a lost fob from the panel.
- BatteryShort range is the first sign of a weak coin cell. Fit the type printed in the compartment with the positive side up.
- EnrollingEnrol it at the panel in device programming and give it a user number. A lost fob should be deleted from the panel at once.
- SafetyDo not leave a fob in a car or a bag that is easy to steal. Tell the monitoring company if you use the panic button.
- Safe useKeep the fob on your key ring, not in the car. If it is stolen, delete it from the panel at once. Test the fob monthly, replace its battery yearly and make sure family members know how to use the panic button and when to use it.

Exact questions
Questions that only have an answer for the ADT Keychain Remote
How far from the Base does the Keychain Remote work?+
ADT states roughly 75 feet under typical house construction, though the company notes actual range varies by the home's construction — a remote that stops responding near the edge of the property is consistent with that documented range limit, not necessarily a fault.
Will pressing Panic on the Keychain Remote call for help if I'm self-monitored?+
ADT documents that for self-monitored customers, the Panic alarm sounds locally only with no emergency-service dispatch. The Panic feature can also be disabled on the remote entirely if it is not wanted.
What battery does the fob use?+
A coin cell; check the compartment.
What if I lose it?+
Delete it from the panel.
What is the first sign of a weak fob battery?+
Short range.
What if I lose it?+
Delete it from the panel.
